Global Legacy System Modernization: Complete VC++ to .NET Transformation with Oracle-to-SQL Server Migration

Client Profile / Industry Context

 

Our client, a leading enterprise software solutions provider operating in highly regulated industries, faced mounting challenges managing aging mission-critical applications. Over the years, their legacy VC++ desktop systems and Oracle databases became difficult to maintain, scale, and integrate into modern cloud-first enterprise ecosystems. To maintain competitive advantage and ensure long-term sustainability, a full-stack modernization program was initiated.


The Challenge / Trigger

The client’s core business applications were originally developed over a decade ago using VC++, MFC, proprietary libraries, and Oracle PL/SQL. These systems supported complex workflows but had become fragile due to:

  • Lack of functional documentation and highly entangled code structures.

  • Tight coupling of business logic within the UI layer.

  • Obsolete custom-built VC++ libraries no longer supported.

  • Difficulty integrating legacy apps with modern web platforms.

  • Rising Oracle licensing and maintenance costs.

  • Limited scalability and future readiness.

With growing business demands, cloud adoption, and user expectations for responsive web-based experiences, a comprehensive modernization was no longer optional — it was a business-critical imperative.
